## 1. Role

### KKW01033SF02DBean.typeModelData()

This method is a **data type router** that implements the `X33VDataTypeBeanInterface.typeModelData()` contract from the X33 Web Client framework. It resolves the Java runtime type (`Class<?>`) for any field defined by the customer (keiyaku) entity within the KKW01033SF screen context. Each of the 36 supported item names (key) maps to a triplet of sub-properties — `value` (the data value, `String.class`), `enable` (whether the field is editable, `Boolean.class`), and `state` (an auxiliary status string, `String.class`). The method follows a **routing/dispatch pattern** with no external service calls or database operations, acting as a static metadata lookup that enables the X33 framework's data-binding layer to configure form fields at runtime (e.g., setting field types, enabling/disabling UI controls). It serves as a shared utility called by the framework itself whenever it inspects the bean's field definitions — for instance, during screen initialization or AJAX partial-page updates.

```

**Processing flow:**

1. **Null guard (L2456–L2458):** If either `key` or `subkey` is null, the method returns `null` immediately.
2. **Separator scan (L2460):** Computes the index of "/" in `key` (the result is stored in a local variable `separaterPoint` but **is never used** in subsequent logic — this is dead code).
3. **Key dispatch (L2464–L2937):** A chain of 36 `if` / `else if` branches compares `key` against hardcoded Japanese item name strings. Each matching key branch then dispatches on `subkey` using `equalsIgnoreCase`:
   - `equalsIgnoreCase("value")` --> `return String.class`
   - `equalsIgnoreCase("enable")` --> `return Boolean.class`
   - `equalsIgnoreCase("state")` --> `return String.class`
4. **Fallback (L2939–L2941):** If no key branch matches, `null` is returned.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The **item name** (display label in Japanese) identifying which entity field the caller is querying. Examples: `"サービス契約ステータス"` (Service Contract Status), `"お客様名"` (Customer Name), `"契約者電話番号"` (Subscriber Phone Number). Determines which of the 36 branches is taken. |
| 2 | `subkey` | `String` | The **sub-property** within the matched item: `"value"` (the field's data value type), `"enable"` (whether the field is currently editable), or `"state"` (an auxiliary status descriptor). Case-insensitive comparison is used. |

**Instance fields read:** None. This method is fully stateless — it reads no instance fields and performs no side effects.

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations**. It is a pure metadata lookup with no calls to service components (SC), command-based services (CBS), database access, or any external methods. It simply evaluates conditional logic and returns `Class<?>` type references.

## 5. Dependency Trace

This method is a framework-level interface method (`X33VDataTypeBeanInterface.typeModelData()`). It is invoked by the X33 View framework during screen rendering and data-binding initialization, not called directly by application logic. The following screens reference the parent module:

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0229 | Framework `X33VDataTypeBeanInterface.typeModelData` -> `KKW01033SFBean` -> `KKW01033SF02DBean.typeModelData` | *(No external calls)* |
| 2 | Screen:KKSV0240 | Framework `X33VDataTypeBeanInterface.typeModelData` -> `KKW01033SFBean` -> `KKW01033SF02DBean.typeModelData` | *(No external calls)* |
| 3 | Screen:KKSV0781 | Framework `X33VDataTypeBeanInterface.typeModelData` -> `KKW01033SFBean` -> `KKW01033SF02DBean.typeModelData` | *(No external calls)* |

Note: `KKW01033SFBean` (line 1358) delegates `listKoumokuIds()` which references `KKW01033SF02DBean`, establishing the bean as the data-type source for the "Customer" item group within the KKW01033SF module.
